Keldoc and Doctolib meet the same basic needs (online scheduling, automatic reminders, 24/7 booking), but their technical architecture and business models differ in ways that affect a practice’s day-to-day operations. Choosing between them depends less on the platform’s brand recognition than on three specific factors: integration with your practice management software, the level of control over patient data, and the actual cost relative to appointments that are attended.
Practice management software interoperability: the criterion most comparisons overlook
An appointment-booking platform that does not communicate properly with a practice’s management software creates duplicate data entry. This issue is more common in practices that use solutions such as Weda, HelloDoc or Medistory alongside an external scheduling system.
Doctolib offers connectors for several practice management software solutions, but the exact scope of synchronized data varies depending on the software. Before signing, request a demonstration using your own tool and check which data is actually transferred: patient identity, appointment reason, slot duration and appointment history.
Keldoc works more as a booking and teleconsultation tool. Clinical or administrative management features often depend on third-party software. The question to ask is not “which scheduling system has the most features?” but which data can be transferred between the schedule and patient record without being entered again. A poor integration with your practice management software cancels out any time savings promised by automated reminders.
We recommend testing the synchronization process over a real working week before committing, including edge cases: late cancellations, changes to appointment reasons and slots involving multiple practitioners.
HDS-certified hosting and patient data portability
Health data hosting (HDS certification) is a regulatory requirement, not a competitive advantage. Both Doctolib and Keldoc claim to provide HDS-certified hosting. The real differentiator is what happens when you leave.
A detailed comparison of Keldoc Pro or Doctolib in 2026 highlights the risk of being locked into a proprietary ecosystem. The ability to retrieve patient histories and contact databases when migrating is rarely tested before signing, even though it determines your future freedom of choice.
Points to check before committing:
- The data export format (CSV, HL7, FHIR) and how soon it will be made available after termination
- The process for deleting patient data in accordance with the rights of access and erasure governed by the CNIL
- Whether reminders and appointment history can be retained in a format that another tool can use
A practitioner who cannot export their data will lose out when switching providers. Portability is not a minor contractual detail: it is a bargaining tool for negotiating fees.
Platform visibility versus cost per attended appointment
Doctolib remains the platform most widely used by patients in France. Its reach is often the main argument for justifying a subscription whose pricing is not public and varies by profession, modules and practice size.
A platform’s overall reach does not automatically translate into useful appointments. Results depend on the specialty, geographic area and actual availability of appointment slots. A general practitioner in an underserved area will fill their schedule regardless of the platform. A specialist in a densely populated area may see a difference, but the cost per new patient who actually attends is the only reliable metric.
Keldoc generally applies a more transparent pricing model for independent practitioners. The trade-off is a lower volume of incoming patients, which can be offset through other channels (the practice website, Google Business Profile, word of mouth).
To decide, compare the following over a period of three to six months:
- The number of new patients who attended after booking through the platform (not the number of slots booked, but the consultations that actually took place)
- The solution’s total monthly cost, including options and modules
- The no-show rate, which varies depending on the quality of SMS reminders and the cancellation policy
Integrated teleconsultation: a module or a complete clinical workflow
Both platforms offer teleconsultation, but the level of integration differs. On Doctolib, the video module is part of the wider ecosystem: scheduling, Assurance Maladie billing and consultation notes are linked in a single workflow. Keldoc also offers teleconsultation, but depending on the subscription, some clinical or administrative components require additional software.
A teleconsultation module is only valuable if it enables third-party payment billing without extra steps. Check whether billing to Assurance Maladie is built in or requires a manual export to another tool.
For practices that offer teleconsultations regularly (several per week), a smooth workflow (patient invitation, virtual waiting room, prescription delivery) is reason enough to choose the solution that integrates best with your existing stack, rather than the one that looks cheapest on paper.
Choosing between Keldoc Pro and Doctolib is not simply a matter of comparing feature lists. Real interoperability with your practice management software and data portability matter more than brand recognition. Test both with your actual setup, measure the cost per completed consultation, and negotiate the data export terms before signing.
